What Fretuno is

Fretuno is an Android learning app for guitar, ukulele and bass players. It combines ear training, practical music theory and fretboard practice in one curriculum. An adaptive plan selects exercises using your goals, previous attempts, accuracy, estimated mastery and review timing. The learning path includes notation, ear training, scales, chords, rhythm, harmony, analysis and improvisation. Lessons provide eight explorer types, including note maps, scales, intervals, chords, harmony paths and a circle of fifths. A tuner supports all three instruments with 18 presets and automatic or manual operation. Progress views show practice activity, accuracy, interval mastery and a note-by-note fretboard map. Core lessons, training and on-device pitch analysis can work offline. The free plan includes five-question sessions, core intervals, the first five frets, two saved strings, tuner presets and Foundations lessons. Pro adds longer sessions, all intervals, up to 24 frets, microphone practice and the complete curriculum.
